Setting the HDD to read-only
When you set an HDD to read-only, recorded video files cannot be written to the HDD.
If multiple HDDs are used, the recorder automatically records to the next HDD not set
to read-only
To set an HDD to read-only:
1. From the menu toolbar, click System Settings > Hard Disk .
2. Select the HDD you want to set to read-only.
3. Click the Edit button
4. Check Read only .
5. Click Apply to save the settings. The HDD is now read-only.
Note: In order to enable recordings on that particular HDD again, you must set the
HDD status back to R/W (Read/ Write). Make sure the HDD storage mode is
"Group" before setting the HDD to read-only.
6. Click Back to return to live view, or continue configuring the NVR settings.
Configuring redundant recording
Setting up HDD redundancy lets your recorder redundantly record a copy of the videos
onto multiple drives as a safeguard against losing all your files in case of disk failures.
This process is also known as mirroring. You must have more than one HDD in your
recorder to set up HDD redundancy.
Redundancy significantly reduces the storage capability of the HDDs. As a result you
need to double your capacity to record video over a given time.
Note: You must set the storage mode of the HDD to Group before configuring the
redundancy. See “Setting up HDD groups” on page 116 for more information.
To set up HDD redundancy:
1. From the menu toolbar, click System Settings > Hard Disk > HDD Information .
2. Select the HDD to be used for redundancy and click Edit.
